Passing a Decimal(str(value)) to a dictionary for raw value

2024/11/20 0:35:29

I'm needing to pass values to a dictionary as class 'decimal.Decimal', and the following keeps happening:

from decimal import *transaction_amount = 100.03
transaction_amount = Decimal(str(transaction_amount))
item = {
'transaction_amount': transaction_amount
}print(item)

Results:

{'transaction_amount': Decimal('100.03')}

How do I attain the raw 100.03 result, rather than Decimal('100.03')?

This is what I want the dictionary to have saved:

{'transaction_amount': 100.03)}

When I do:

print(transaction_amount)

The result is as expected:

100.03

So where am I going wrong?

I don't see any reason why this question should be downvoted.

Answer

When you ask python to print an object, it'll print the textual representation of that object.

Here your variable item is a dictionnary, so its representation is as follow:

{ key: value [, repeat]}

If you want the value inside your dictionnary, you would have to go at the specified key like so :

print(item[transaction_amount])

So basically, your code was fine and your use of decimal too, but you weren't testing it the good way. ;) Happens a lot.

Edit: It's worth noting that, since what you are getting within the dictionnary object is Decimal(100.03), even when printing the value of the key-value pair as I showed previously, you won't get a pure 100.03, but probably Decimal(100.03).

I'll search some documentation as to how to get the string. Welp apparently no, it should work like a charm.

Edit: I didn't get the question (which has been edited since then) right.
However because of the extended conversation in the comment section, it'll remain here.
